Abstract

The sheet bending with large radius of curvature is analyzed with both theoretical and experimental methods. Sheet bending in elastic limit is accomplished by the plastic deformation of flange. The springback model is developed theoretically and the effects of the factors are evaluated. The prediction accuracy of the model is also evaluated by comparing with the experimental data. Finally, an algorithm to design the sheet-bending die is suggested for usage in industry.
